Active oxygen species might be involved in skin tumor growth, but their exact role is unclear.

This review discusses trends in testosterone therapy use for male hypogonadism and reports no new clinical results, noting a shift towards more convenient and physiological treatments.

In this study, researchers observed that human sebaceous glands can regenerate in a mouse model using transplanted human skin, potentially offering a tool to study sebaceous gland biology and regeneration.

This study reported that derivatization with 5-butylpicolinic acid improved the sensitivity for detecting testosterone and DHT in saliva using LC-ESI-MS/MS, with minimal interference from the saliva matrix.

This study found that co-administering glucocorticoids with 5α-reductase inhibitors exacerbated the adverse metabolic effects of glucocorticoids in healthy men.

This research found that Leydig cells significantly rely on synthesizing omega-6 HUFAs to support male steroid hormone production, highlighting a new role for these fatty acids in the male reproductive system.

Diphenyl ethers can potentially reduce excess oil production when applied on the skin, helping treat conditions like acne.

This study found that menopause alters hair lipids and reduces hair quality, with hormone replacement therapy mitigating some changes.

This study observed that male and female epidermis differ significantly in total lipid and phospholipid levels during different stages of the hair growth cycle.

This study suggests that vitamin A may inhibit hair follicle stem cells during refractory telogen in a dose-dependent manner, based on retinyl ester levels and vitamin A metabolism protein localization in mice.

This study found that cream ingestion increased NFκB activation in women with PCOS, which was associated with insulin resistance and higher ovarian androgen levels, regardless of obesity status.

In this study, despite morphological differences in the hair growth cycle stages, the lipid composition of the epidermis and dermis showed no significant variation, though water content and cholesterol levels differed between these skin layers.

This study identified pantolactam based compounds as effective topical antagonists of the androgen receptor, reducing sebum components in a hamster model.

This study found that certain steroidal compounds, especially 10a–10c, demonstrated strong antiandrogenic activity by binding to the androgen receptor and reducing prostate weight in a hamster model.

This study found that the lipid composition of the epidermis varies significantly throughout the hair growth cycle and after applying methylcholanthrene, with notable differences observed between hyperplastic and carcinomatous conditions.

Higher LDL lipids may increase alopecia areata risk, while higher triglycerides may decrease it.

This study demonstrated that herbal therapy with oil extract increased triglyceride content in dog hair, suggesting potential benefits on coat quality that require further investigation.

This study found that both hard and soft selenium disulphide-based detergents significantly increased triglyceride levels in human hair, suggesting enhanced sebum production with reduced lipolytic activity, but showed no significant differences between their effects.

This study investigated pangolin skin genetics, finding that while sweat gland-related genes are not inactivated, several genes related to sebaceous gland function are, which highlights complex evolutionary adaptations in mammalian skin.

This study observed that the molecular structure of keratins in hair fibres' discrete transition zone differs in breast cancer patients, with altered lipid ester absorption bands reverting post-cancer removal.

In this study, researchers identified two mechanisms of lipid loss from hair when exposed to surfactants, with the mechanism depending on the lipid's hydrophobicity.

This study developed a novel hydrogel that improved healing in diabetic infected wounds on mobile sites by controlling infection, inflammation, and mechanical stress, promoting skin regeneration without excess scarring.

This review highlights Croton tiglium's dual therapeutic and toxic properties, noting its potential for hair growth promotion through PKC-mediated pathways, while emphasizing the challenges posed by its toxicity for safe clinical use.

This review consolidates evidence on Croton tiglium's bioactive compounds and effects, discussing its potential uses in treatments like hair-growth formulations, yet emphasizes the significant safety challenges due to the plant's inherent toxicity.

This review highlights jojoba oil's unique composition and its growing therapeutic applications, noting its antioxidant, anti-acne, antidiabetic, and antibacterial properties, as well as its use in various pharmaceutical formulations.

This study evaluated the protective effects of a hair conditioner containing rice derivatives on natural Caucasian hair using various analysis methods and found that the conditioner, especially with rice germ oil GX-N, effectively improved hair properties even under stress conditions like irradiation.

This study on Sdr16c5/Sdr16c6-null mice found that inactivating these genes significantly increased Meibomian gland secretions and altered lipid profiles but had a subtle impact on sebogenesis, suggesting the genes control a bifurcation point in meibogenesis pathways.

This study found that sensitive scalp is characterized by increased pH levels, redness, altered sebum composition, and a disrupted microbiome, suggesting these features could inform treatment approaches.

Mutations in Far2 mice cause hair loss due to sebaceous gland issues.

Daylight photodynamic therapy is effective and well-tolerated for treating actinic keratoses with minimal side effects.
